similar to: [PATCH 2/5] Xen/MCE: vMCE injection

Jan, This patch just used to stick all 1''s to MCi_CTL, it should not involve much argue, so I sent it separately. Thanks, Jinsong ==================== Xen/MCE: stick all 1''s to MCi_CTL of vMCE This patch is a middle-work patch, prepare for future new vMCE model. It remove mci_ctl array, and keep MCi_CTL all 1''s. Signed-off-by: Liu, Jinsong

Hi, This is updated xen vMCE design foils, according to comments from community recently. This foils focus on vMCE part of Xen MCA, so as Keir said, it''s some dense. Later Will will present a document to elaborate more, including Intel MCA and surrounding features and Xen implementation. Thanks, Jinsong

Hi, Jeremy and all This small patch lets pv ops guest handle machine check trap. When non fatal mce error happens, xen will inject vMCE# to the impacted pv ops guest. This patch allows pv ops guest could receive machine check trap and enter its own machine check handler.

This patch series is a reworking of a series developed by Mukesh Rathor at Oracle. The entirety of the design and development was done by him; I have only reworked, reorganized, and simplified things in a way that I think makes more sense. The vast majority of the credit for this effort therefore goes to him. This version is labelled v13 because it is based on his most recent series, v11.

We seem to find an interesting bug, but not for sure. Each time before xen returns to hvm domain, it checks local_events_need_delivery to see whether any events pending and if yes, inject event by callback_irq into the virtual interrupt controller. However, the interesting point is, we never found any place, either in xen or in PV drivers, to clear evtchn_upcall_mask at any time. The initial

Keir, It''s a resending patch for the timeout mechanism to deal with the shared interrupt issue for vt-d enabled hvm guest. We modify the patch following your comments last time and make some other small fix: 1) We don''t touch the locking around the hvm_dpci_eoi(). 2) Remove the HZ from the TIME_OUT_PERIOD macro which may confuse others. 3) Add some

I last posted this back in April to critical acclaim (AKA near total silence). I''m not sure who looks after tools/include/xen-foreign. I had thought it was Jan but I think I was confused and was thinking of the semi-related xen/include/compat stuff. IOW I think nobody felt "responsible". Unless there''s any objection lets just treat this as coming under tools. The

Changes from v3: - mini-os configuration files moved into stubdom/ - mini-os extra console support now a config option - Fewer #ifdefs - grant table setup uses hypercall bounce - Xenstore stub domain syslog support re-enabled Changes from v2: - configuration support added to mini-os build system - add mini-os support for conditionally compiling frontends, xenbus -

Hi, Keir and Jeremy This small patch is for controlling machine check related XEN log output. When set mce_verbosity=verbose in command line, all mce related log will be printed. Otherwise, those logs will be not be printed. This patch should solve too many mce logs printing problem when guests keep polling machine check status. Thanks a lot for your help! Regards, Criping
